[Paraview] PV 3.14.1 crashes when disconnecting a dataset

[Cory Quammen]

I don't know if this is related, but I just found a crash when
shutting down ParaView. I'm running in Debug mode under Visual Studio
2008 64-bit and I have commit 0f43430ddb988dbb05b8c3ff4bf414dc79608c4a
checked out. When I run ParaView and close it immediately without
doing anything, I get a crash in pqProxy::clearHelperProxies() (lines
170-171)

  if ( this->getServer() && this->getServer()->session() &&
       !this->getServer()->session()->IsMultiClients())

The NULL check for this->getServer()->session() succeeds because
session returns a pointer with the address 0xfeeefeeefeeefeee which in
Debug mode means it has been deleted.
